Cannot click next in Asset Studio when creating an icon

Not sure where to post this issue I have with Android Studio IDE, I hope it can be answered here.
When I open the Asset Studio in Android Studio by right clicking on my Android Module and selecting new -> Image Asset I cannot get past the first screen. Even when I leave this default, when I try and press next the Asset Window start shaking shortly after a second or two.
I encountered this problem with a prior version of Android Stuido but an update to the latest version did not help.
I tried updating the android SDK and build tools since they are obviously related but without success.
I tried restarting Android Studio but the "bug" still remains.
Perhaps I am doing something wrong, I created a video of my workflow and the issue I am encountering.

I had the same problem.
In the Legacy tab, I set the Google Play Store Icon to No and I could pass the first screen.

I had exactly the same problem while I was trying to create adaptive icon from vector graphics.
What helped me was that I need to set Size to 108 dp x 108 dp when I imported Vector Asset (res -> right click -> New -> Vector Asset).

I have faced the same issue with vectors that had a dashed line. Android Studio doesn't support dashed-strokes by default. You can check what is not supported in this link Dashes stroke-dasharray in Android Vector. So in such cases Android Studio just doesn't show any error upfront.
In your case I see its happening even for normal vectors.
To check why its failing notice every time it fails the exclamation mark at the extreme bottom right of Android Studio turns red and flashes. Just close pop up window of Android Studio and click on the red exclamation mark. It will give you the reason why its failing. Although there was nothing much I could do about it maybe you can figure out whats wrong.

I know it's been answered but here's another thing that might fix someone else's problem when adding an asset and getting the weird shaky window error: check the asset dimensions you're importing.
I was trying to add a Vector Asset with dimensions about 23dp x 1077dp (really big height and small width), and for some reason Android Studio didn't accept it. After changing it to a dimension bigger than 170dp x 8137.3dp (it scales automatically) it worked. Then I went on the .xml file and changed it to a dimension I wanted, preserving the proportion of mostly 200dp in width or height as prompted by Lint in a warning.
I don't really know why it worked but I managed to add the asset. If anyone knows it, feel free to explain.

Steps:
1) Have you tried setting it manually through file explorer/directories etc.?
2) Maybe try a drawable importer? Like this.
3) Have a look at this answer, it might help.
4) Try completely uninstalling Android Studio, re-download and install again, if all else fails.

As per your project structure, I believe this is not a native application.
That's right, Flutter projects are not Android projects. Many Android tools are enabled only for projects that have an Android facet. Adding that to Flutter projects causes many problems, so we don't do that and this functionality available for only in native android application.
Furthermore,If you want to use may be it'll help you.
Open android studio File->Open folder->navigate to your flutter project and select the Android folder. Wait for it to sync, then navigate inside the Android studio folder and find the res folder right click on it and choose New you will see the Image asset studio.

This happened to me and the problem was that the dimensions of my source image were too small, which I think is the takeaway from all the other answers as well.

In my case the issue was caused by some unusual project structure, including some source directories added manually within the module.
The only solution was to create a new sample project in Android Studio, use the Asset Editor, generate all the assets to finally copy those to my "unusual" project.
One could also read the IDE (Android Studio) logs to see exception that are being thrown when the editor windows shakes as it's described by the Author of this thread.

Android studio pixelated preview

After updating Android studio to version 3.1.2 an issue popped up where the preview image is, pixelated/blurry. Can anyone help me fix this issue?
This is how the image is rendered

I have encountered the same problem in Android Studio 3.3 but fortunately I've managed to find a solution. You have to go to "Help" and click on "Edit Custom Properties". It might ask you to generate a file if it doesn't already exist. Once this properties file is made, you will need to write "hidpi=false" (no quotations). Save it and restart Android Studio. When you open it again , you still need to do one thing: go to File then Settings, type font in search box, select font from editor then change the size of font to 15. (or what ever size you prefer). That's all.

I'm not sure weather it will work for your scenario. I had a issue with icon pixels and I followed this.
I hope it will help you.
Create a drawable-xxhdpi directory and add all your images in that and try.
NOTE : I'm not sure that this process helps you or not.
link help you to create drawable-xxhdpi directory

I'm having the same problem and it is somehow annoying i opened a bug ticket and i will wait for there response here is the ticket link : https://issuetracker.google.com/110463869

I solve this problem pretty easy after learning documentation.
You need to change your scale display parameter. Because Android Studio supports only certain scale. Use 100% or 200% and your design tab in Android will be sharp again

Xamarin: Image in ImageView doesn't appear in my Design but appear on AVD?

I have a problem in preview my image in ImageView in Xamarin Visual Studio in the design. However, the image appear on AVD when run the solution on it.
Some screen shots are below.
As you see, I added two images and set the src correctly for them but they doesn't appear in the design:
And when run the code on AVD, all images were appeared:
I want to make the images appear in the design to make whatever changes I need before upload the code on AVD.

After a lot of searches I found the solution on Microsoft site here
https://msdn.microsoft.com/en-us/library/mt613162.aspx

If there is a new version it will appear to install.
All thing go right After installing the latest version.

Preview tab is not visible in Android Studio

I have installed an android studio and tried to create my first project. But preview tab is not visible.
I checked it in the View -> Tools Window but the preview is also not present there.
Even Design/Text tab is not visible in the android studio. I checked the earlier posts in stackoverflow but have not been able to resolve this problem.
Like this one : Where is Android Studio layout preview?
Not able to show you the image as this is my first question and I have only 1 reputation. :(
Please suggest a way to find it.
Thanks in advance

As per the screenshot your project structure is not as per it should be. Reason is clearly visible in the picture, Your SDK buttons in tool bar are grayed in screen shot that means there is some problem in the SDK path.
please set your SDK path from
File > Project Structure > Android SDK
And after that sync your project with gradle using the tiny gradle button available in tool bar.
Not even the preview, you will not see any android specific tabs if your sdk path is not correct.
For reference your studio will look like this after correct sdk

I had the problem of not seeing a preview tab, or the design and text tab. After playing around with it for a while I found that the problem was that my Gradle was messed up. I went to the Gradle Console (bottom right corner of the screen) and opened it. I asked me to import Gradle project (the one I was working on) and it worked. Sorry if that doesn't make sense, I am very new to Android Studio

Android Draw9patch is missing?

Can anyone please explain why the draw9patch isn't on my computer despite ADT and all? A search after the jar-file doesn't give any result.
I believed it should be installed by default. AFAIK, nobody else has had this problem.
Can anyone help? I've tried making 9 patches on my own using Paint.NET by adding one black pixel to the left and top of the image, but as I am new to Android, I can't make it work. I even tried a utility called better9patch to no avail. I am getting quite frustrated right now as I think the graphics of a program should be the least of your concern when programming.

Infact, the popular draw9patch application is now available as a feature in the android studio application itself. If you try to open any files with a .9.png extension in your project, it will be opened in a 9 patch drawer perspective. Here is a screenshot.

You should download "draw9patch" folowing this link: https://androidstudio.io/downloads/tools/download-the-latest-version-of-draw9patch.jar.html.
Afterwards you extract the file and it will work.

open up your terminal navigate to sdk/tools. and type
chmod +x draw9patch
./draw9patch
hope it can fixed.

You can use Android Asset Studio
Simple nine-patch generator. This is web application.
A collection of tools to easily generate assets such as launcher icons
for your Android app.
Project page: https://romannurik.github.io/AndroidAssetStudio/

The program should be under android-sdk/tools/draw9patch. If you want to create the image manually, you need 1px-wide transparent border all around the image with black dots on those empty spaces to denote patches
